Performance Testing
Introduction
Performance Testing
Performance testing is how we find out how much load an application can handle. This guarantees that the program won't crash as a result of loads from several users at once. An application must be able to withstand the concurrent use of several users in order to be considered fully functional, which makes performance testing a crucial kind of non-functional testing. Users will reject the program and search for other choices if it does not function as intended under such load situations. Consequently, there will be a decline in business. Our testers use performance testing to assess an application's responsiveness, resilience, scalability, stability, speed, and application size for a given workload.
We identify the “tipping point” of the application, by subjecting the application to huge stress. We check the system failures, data security issues, and privacy policy breaches.
We analyze the scalability of the existing system and find the weakness of the product using Volume Testing techniques. It helps in finding any unwanted product configuration and provides necessary information for technical maintenance.
If you want to check the strength of your application or the server’s strength you will need to find out how much load, in terms of the number of users the application can handle. We use the Performance Testing techniques, to check the load an application can handle.
Why is Performance Testing Important?
- Ensures Stability: Verifies that the system can handle expected and unexpected load conditions.
- Improves User Experience: A slow or unresponsive application can frustrate users and cause them to abandon it.
- Validates Scalability: Ensures that the system can scale to meet future demands.
- Identifies Bottlenecks: Helps in pinpointing performance issues like high response times, memory leaks, and CPU overloads.
Tools used
Tools we use while doing Performance Testing
- JMeter: JMeter by Apache is used to perform load tests and to measure the performance of websites. It is open-source software written in Java and is used to test both web and FTP applications if the system supports Java Virtual Machine. We at Precise Testing Solution use JMeter to conduct Performance Testing.
- Load Ninja: Load Ninja is used to creating load tests that are scriptless. Here real browsers are used instead of emulators. Load Ninja helps in conducting high-quality tests in less time and is hosted on the cloud.
- LoadRunner: LoadRunner from Micro Focus, later acquired by Hewlett Packard Enterprise is the oldest and most popular testing tool for performance testing. Applications are subjected to various levels of load to see how they behave, before going into production. Load testing before the application goes live is extremely essential because, if the application performs badly in a live environment, it will be rejected and therefore lead to a loss in business.
- WebLoad: It is an enterprise-scale load testing tool from Rad View software. It is used to test scalability, performance, and verifiability. The script is recorded in Selenium and then exported to Web Load. It is a web and mobile testing and analysis tool.
